Hi Andrew,
I did not asserted thet GPS Area circular, it was just a question I put to
myself, but now I have a more clear idea.
First I provide a good definition for understanding GPS measures and how
they are used as locations or other uses on GIS or other applications.
"GIS (Geographic Information Systems) is tool to display and analyze
information geographically. GPS (Global Positioning Systems) is a
technology that uses satellites to give one its position on the Earth with
the aid of a GPS device or unit. GPS can be incorporated into GIS by using
a GPS device to collect points, lines, or polygons, which can be imported
into a GIS application for future analysis and interpretation."
So I note GPS instruments can just provide single location (I verified
this with an expert), then lines and polygons are used as a collection of
points to describe something relevant for a GIS system.
Cities are usually indicated with their centre (location), but a location
could be even more precise (e.g. a building).
Lines are used for distances.
Polygons are usually used to associate other information (e.g. population
density), but "Area" I think is a better term.
The circular area is more related to the precision of a GPS that could be
some meters.
Finally I would see something like this for an Area:
AreaCoordinate 0..1 (new ABIE)
- AreaName 0..1
- AreaDescription 0..1
- LocationCoordinate 0..n (ASBIE)
Cheers,
Roberto
